TRACTION-PLOW.

To all whom it may concern:

Be it known that I, SEABURY N. E. PRIDDY, citizen of the United States, residing at Findlay, in the county of Hancock and State of Ohio, have invented certain new and use ful Improvements in Traction- Plows, of which the following is a specification.

This invention relates to traction plows and is designed as an improvement over the common mold board, disk, or other forms of plows, which have been used heretofore.

One of the objects of my invention is to provide a traction plow which will plow or prepare for seeding a large'section of the ound at one time.

A further object is to provide a traction plow having a rotary cutting member which Will be under absolute control of the operator at all times, which is strong and durable and can be operated effectively with an expenditure of a minimum amount of power.

In carrying out my invention I provide a traction plow having a large rotary cutter in the form of a hollow drum or cylinder which has at its periphery a large number of transverse cutting blades or knives and which is rotatably mounted in a frame pivotally supported in some manner upon the truck, which frame arranged to be raised or lowered about its pivotal axis, so as to vary the depth of cut or to raise the cutting member out of operating position.

The invention relates particularly to the form and construction of the cutting memher, and to the means for supporting, bracing and driving the same. As the cutting member is preferably constructed it comrises three or more flat rims or rings of arge diameter and arranged in parallel planes, across which rings the cutting blades extend. The cutting member is supported in the pivoted cutter frame by series or sets of grooved rollers, which are arranged to engage the inner peripheries of. these rings, the rollers being supported in some manner upon the cutter frame, and it is preferably driven by means of toothed members which are secured to the flat faces of the rings, and are engaged by gear members connected by a suitable driving mechanism to the engine shaft. r

The invention also consists in certain novel details of construction and combination and arrangement of parts, which will be described in the specification and set forth in the appended claims.

For a better understanding of my invention reference is had to the accompanying drawings, in Which--- 7 i p Figure 1 is a side elevation of a traction plow forming the subject matter of my invention; Fig. 2 is an enlarged plah view of the cutter member and a portion "of the truck frame and driving mechanism; Fig. 3 is a plan view of the truck frame includ-' ing the engine and other parts of the operating and driving mechanism, the latter'being shown somewhat conventionally and parts of the raising and lowering mechanism of the cutter frame being removed for the sake of clearness; Fig. l is a sectional elevation" substantially along the line 4-4 -'of Fig. 2

- showing in detail a portion of the cutting member and one of the combineddriving gears and supporting rollers; Fig. 5 is asectional elevation substantially along the line 5-5,of Fig. 2 looking in the direction indi cated by the arrow, showing in detail a por-.

tion of the cutter and one of the-grooved supporting rollers; and Fig. 6 shows a portion of the modified form of cutting member.

Referring now to the figures of the draw ing, 10 represents the traction truck ha ing two longitudinal side beams 11 and ]2,which support front and rear axles l3 and 14, on which are mounted the front ground wleels orted on the truck is a boiler 16 and driv ing engine 17, which as will be explained is geared to the rear driving axle and to the cutting member. the outer ends of the rear axle 14: by means of box bearings 18 is a cutter frame 19, which is rectangular in form and comprises two arms 20 and 21 spaced a' considerable distance apart and joined at the outer free end by a cross member 22. Rotatably mounted upon the arms 20 and 21 of the piv oted'cutter frame is a cutting member in the form of a hollow drum or cylinder, which consists in this case of a number" of spaced parallel flat rings or rims, three being shown inthis case, designated respectively 28, 24' and 2,5, and a number of flat cutter blades or knives designated in Figs. 1, 2, t and 5 as 26. These cutter blades which are formed of tempered tool steel and are shaf-penedor beveled at the front edges, may be arranged in various ways upon the rings, either car'- ried straight across from one end of the cutting member to the other or they. may be diagonally arranged. In the preferred con- Pivotally mounted upon their ends which are bent at right angles along the sides thereof by means of bolts or rivets 27.

Secured to the outer rings 23 and 25 of the cutting member intermediate the cutter blades '26 are clearance cutters 28, the purose of which is simply to form a clearance in the earth for the outer rings when the cutting member is in operation. Each of the rings ofthe cutting member is provided on one side with a circular toothed driving member 29 which is preferabl i a separate steel casting bolted thereto. I desired each circular toothed member may be formed of a plurality of separate segments. arranged end to end to form a circle. While I have shown the cutting member as having three rings it is to be understood that it may be formed of a different number of rings, the number of rings depending upon the size of the cutting member or the conditions to be encountered.

As was stated before the cutting blades instead of being spirally arrangedinay extend straight across the cutting member. This construction is shown in Fig. 6. The cutting member here shown has three flat rings 23", '24 and 25 which support cutters 26". The cutters are secured to the outer rings 23 and by rivets 27 and at the middle of the cutting member the cutters are secured 'to flanges of T-irons 26", the

vertical flanges of which are secured to the middle ring 24 by flat plates 26. Ashore shown each of the cutters consists of two parts which extend from the outer rings to the middle ring.

The cutting member is well braced and firmly supported so as to rotate in the frame by means including sets of grooved rollers arranged to engage the inner peripheries or edges of the rings. In this case there are three sets of the rollers engaging the inner peripheries of the rings at different points as will now be described. Extending trans-- versely of the frame through the cylindrical cutting member and supp ed in heirings 30 on the top of the beans Fifi and 2] is a shaft 31, which serves both a driving shaft and a supporting shaft. Mounted on this shaft in the planes of the rings are three driving and supporting members 3:2, each having a toothed portion 32 which enages the circular toothed member on the ace of the corresponding ring so as to form a driving connection between the shaft 31 in the form of a hub which is provided with a groove which engages the inner periphery of the ring. Also supported in bearings 33 on the to of the beams 20 and 21 and extending t rou h the cutting member a suitable distance Tom the shaft 31 is a second shaft 34 on which mounted a second set of grooved supporting rollers 35 which also engage the inner edges or peripheries of the rings. Located near the lower portion of the cutting member and extending through the same is a third shaft 36 on which are mounted a third set of grooved supporting rollers 37, said shaft being braced and supported from the cutter frame by means of rods 38, which extend upward and are secured at their upper ends by means of nuts 39 in an angle iron 40 extending transversely of and secured to the underside of the beams 20 and 21 of the cutter frame adjacent and below the'driving shaft 31, and also by rods 42 which extend upwardly and forwardly and are secured at their upper ends by means of nuts 43 in an angle iron 44, which extends transversely of and is secured to the lower side of the beams 20 and 21 adjacent and below the shaft 34. Thus it will be seen that the cuttin member is supported by three sets of rollers of three each and that each ring is engaged at three points in its peri h erv. It is to be understood that the num er of sets of supporting rollers may be varied to suit requirements.

The mechanism for driving the traction plow and for operating the cutting member will now be described, special reference be ing had to Figs. 1, 2 and 3. The crank shaft of the engine, shown at 45, is provided with a gear 46 shown most clearly in Fig. 3, which can be connected to the shaft by a clutch 46, the clutch operating mechanism not being shown. The gear 4F. meshes with a master driving car 47 which is mounted upon a shaft 48 suitably supported upon the truck and engine frame. Fixed to the end of the shaft 48 is a sprocket wheel 49, which drives the rear axle and rear ground wheels so as to move the plow along the ground by means of a sprocket chain .70 and a sprocket member 51 which is on the rear axle intermediate the ground wlicel and the truck frame, said sprocket member 5 being a part of a differential mechanism 52 of a well known type.

The cutting member is rota lowing manner.
